ABSTRACT:
An RC network is integrated in a semiconductor circuit chip and is connected between an input pad or pin and a ground node coupled to a substrate of the chip. The RC network has a plurality of resistance elements, a plurality of capacitance elements and a plurality of connection/isolation elements, which are provided in each case between at least one of the resistance elements and the individual capacitive elements. The inventive circuit configuration enables an optional and independent setting of the input capacitance and of the input resistance of the semiconductor circuit chip, depending on the connection/isolation state of the connection/isolation elements.
